Use the same Magnet to easily destack and handle

Sheet metal unstacking with PES magnetic tools

Robotic destacking of metal sheet with magnetic grippers may sometimes cause some issues. Indeed, the magnetic field may reach several sheets at a time and residual oil or other lubricants between successive sheets make them stick together.

Thanks to Magswitch M10AY ASC magnetic grippers PES offers a shallow field solution that saturates at 1mm depth! Benefits of pneumatically actuated magnetic grippers (flexibility, reliability, energy efficiency) come to serve your destacking application. Used with the sheet fanner tool which allows performing a pre-separation of the sheets on the stack and avoids blanks sticking issues, this solution can reach up to 100% single sheet destacking performance in all conditions. 

This technology is quite empirical, tool dimensioning then needs experience-based expertise which PES can offer. Do not hesitate to contact us for your next project. The offered power range is quite large and those units can equip the smallest collaborative robot as well as the larget industrial one.
